rlhe invention relates to heat exchange ldevices and has among its various objects the provision of a construction which is castl to provide a plurality of vertically extending heat radiating ribs and a transverse web with the material at the juncture oi the ribs and webs formed to produce a fluid passage which communicates with transversely arranged fluid passages respectively providing an inlet and an outlet for said tubular passages.

A further object of the invention is to arrange these ribs, web and iiuid passages relatively to each other so that a luted construction is produced between the ribs to thus provide means causing air to contact with the Huid passages and become heated as it travels along the iiutes.

lt is a further object Vof the invention to combine heat radiating tins with a. structure such as that above described and to either directly connect said fins with the device or to mount these iins upon a duid conducting tube, the latter of which is in communication with the interior ofthe device.

ln addition to the above, it is an object to construct theviins so that they, in effect, provide vertically extending open-ended tubes for conducting air to be heated in vertical columns along the heat exchange device, the Ens being preferably located at the lower end of the structure, the upper end ci the structure being provided with an apertured eX- tension providing a grille of which openings therein communicate with the space above the tins to thereby allow heated air to escape into the room to be heated.

Another object of the invention is to provide a construction which may be arranged and housed in a recess provided in a wall or to `1 arrange the device in a metallic casing which may be loca-ted in the r'ecess or be arranged at one side of the wall.

The invention has these and other objects, all of which will be more readily understood when read in conjunction with the accompanying drawing which illustrates various constructions of which' the invention is susceptible, it being obvious that other changes and modifications may be resorted to without departing from the spirit of the appended claims forming a part hereof.

ln the drawing, Fig. l is a Jfront elevation of a device constructed according to the invention;

Fig. 2 is a section taken on the line 2-2 ot Fig l on a slightly enlarged scale;

Fig. 3 is a section taken on line 3--3 o Fig. l;

Fig. l is a section similar to Fig. 2 showing a modified arrangement;

Fig. 5 is a section taken on line 5--5 of Fig. ll; and

Fig. 6 is an enlarged sectional view taken through the upper transverse Huid passage, and web.

'lhe structure embodying the invention is designed to be arranged in spaced relation to the iioor of the room to therebyl provide an opening l0 through which a portion of the relatively cool air located at the lower part of the room may pass into the casing or recess in the wall generally designated l2 and contact with the device generally designated ll, be heated and be discharged through openings such as i3 providing a grille arranged at the upper end of the structure. A tank or water container i4, having one wall such as l5, is employed which provides container for.

water to humidity the air in the room and' deiect the heated air through the openings of the grille. 'lhe structure contemplates the utilization of a removable cover i6 for the tank or container lil, it being understood that the structure also is provided with a plurality ot openings such as i7 through which the vaporI may escape `troni the water contained in the tank 14.

llt Wili be noted by referring to Figs. l, 2, and 5 that this structure includes a plurality ot vertically extending ribs 18 and a transversely extending wall or web 19, the juncture ot the web and ribs l being hollow to provide a plurality of vertically extending iuid passages 20. rllhe walls of the iiuid passages are connected with the web 19 in a manner to provide a plurality ot vertically extending iiutes 21. the latter or" which are formed by the combination ot elements including the heat radiating ribs 18, web i9 lil@ 1 vice Constructed as above explained.

and the Walls of the fluid passages 20. These flutes are provided to conduct air in a vertical direction and maintain. contact between theV air and the duid passages 20 during its travel and thence discharge the air in a 5 heated condition near the openings provided in the grille 13.

As before stated, the invention contemlates the combination of heat radiating and eatconducting fins and a heat exchange 'idlefins shown in Fig. 3 and designated 22 are preferably of U-shaped formation and thus, in effect, will provide a plurality ot vertically extending tubular passages 23. In the structures such as that illustrated in Fig. 3, it is contemplated to connect the opposite. ends of the U-shaped members with the heat exchange device, generally designated 11 having iiutes, by casting said ends of the shaped fins in lugs designated 24 Whi ch extend from one face of the heat radiating device. It will be noted by referring to Fig.-

3 that when U-shaped heat radiating fins such as those just described lare employed and arranged in themanner shown in Fig. 3 that the spaces produced between these heat radiating fins also provide passages such as which also act to conduct the heated air in a column parallel with the flutes and to- Ward the openings 13 in the grille.

Supply and return lines are, in the present construction, respectively designated 26 and 27. It may be here stated that the heat ex- 85 change device formed of the ribs, web, and

Huid passages such as 20 and the iiutes 21 are connected at opposite ends by transversely arranged iuid passages respectively designated 28 and 29 which Will thus provide n means for supplying heating fluid to the tubular passages 20, it being understood that the supply and returns 26 and 27 are connected with transversely arranged passages 28 and 29.

45, The structure shown in Fig. 5 substantially vide means for introducing heating uid to the tubular passage to thus heat the fins mounted upon the tube. In the structure shown in Fig. 5 oppositely extending vertically disposed ribs respectively designated 30 Y and 31 and a transversely disposed web 32 are employed. The material of the casting at the juncture ot the lribs and webs is hollowed to provide'ver'tically extending fluid passages 33 similar to the iiuid passages C5 2O of the structure shown in Fig. 3.

The tlu-id passages 33 of this construction communicate with transversely arranged fluid passages respectively designated 34 and 35, the latter of which receive heating Huid through the agency of the supply and return pipes similar to those designated 26 and 27 shown in Fig. 2.

As betore stated, the structure shown in Figs. 4 and 5 also contemplates the utiliza'- tion of heat radiating and conducting tins.

These fins are designated 36 and are mounted upon a transversely arranged tube 37. This tube is connected in any suitable manner to supply heating duid to the tube. In the present instance, this tube 37 lis elongated in cross section as shown in Fig. 4 and has its opposite ends respectively connected to the supply and return designated 38 and 39 which connect and communicate with the interior of the heat exchange device generally designated 40. These tins 36 are each provided at their opposite ends with the flanges res ectively designated 41 and 42 and thus, in e ect, provide a plurality of vertically arranged tubular passages.

From the foregoing description of the construction, it is manifest that a simple construction is provided which ma be cast and produce a plurality of vertica ly extending heat radiating ribs such as 18 which are connected to a transversely arranged web such as 19 and in which the juncture of the ribs and Web is hollowed to form a. tubular passage such as 20, the ribs and the walls of the tubular passage and the web being connected together in a manner to provide the vertically extending flutes 21' which produce an eiective construction for quickly heating and conducting the heated'air in a manner so that it will be quickly heated prior to its discharge from the recess or casing in which the heat eX- change device is located. It is also evident that by constructing the flutes so that a curved transverse formation is produced that the heat radiating surface is materially increased.
